# `memfaultd`
`memfaultd` is a daemon that runs on your device and collects crash reports and
metrics. It is the core of the
[Memfault Linux SDK](https://github.com/memfault/memfault-linux-sdk/blob/kirkstone/README.md).
## Overview
`memfaultd` supports several features to help you maintain and debug your fleet
of devices:
- **Crash reporting**: When your device crashes, `memfaultd` collects a crash
report from
[Linux Coredumps](https://man7.org/linux/man-pages/man5/core.5.html). For more
information, see the
[Coredumps documentation](https://docs.memfault.com/docs/linux/coredumps).
- **Metrics**: `memfaultd` collects metrics from your device and uploads them to
Memfault. For more information, see the
[Metrics documentation](https://docs.memfault.com/docs/linux/metrics).
- **Reboot reason tracking**: `memfaultd` detects various reboot reasons from
the system and reports them to the Memfault Dashboard. Users can also provide
a specific reboot reason before restarting the device. For more information,
see the
[Reboot Reason Tracking documentation](https://docs.memfault.com/docs/linux/reboot-reason-tracking).
- **OTA Updates**: `memfaultd` supports [SWUpdate](https://swupdate.org/) out of
the box and is able to configure it to talk to our hawkBit DDI-compatible
endpoint. For more information, see the
[Linux OTA Management documentation](https://docs.memfault.com/docs/linux/ota).
- **Logging**: `memfaultd` collects logs from your system. For more information,
see the [Logging documentation](https://docs.memfault.com/docs/linux/logging).
